In case you have trouble with dynamic loading of shared libraries,
you will find that a static gdbserver comes in handy.
However, it has been noticed at least on x86 that enabling this
option produces an invalid gdbserver binary. It is linked with
"-static -Wl,--dynamic-list=..." which
# (a) requests invalid program interpreter
# (b) crashes glibc/uClibc-ng and does not work with musl
# See https://sourceware.org/ml/libc-alpha/2017-03/msg00267.html
It is possible it would work with other architectures, hence it is
not completely removed. Use with care and report to the mailing list
if the resulting gdbserver works.

commit 5a6c3296a7a90694ad4042f6256f3da6d4fa4ee8
Author: James Clarke <jrtc27@jrtc27.com>
Date: Fri Jan 19 17:22:49 2018 +0000
gdb: Fix ia64 defining TRAP_HWBKPT before including gdb_wait.h
On ia64, gdb_wait.h eventually includes siginfo-consts-arch.h, which
contains an enum with TRAP_HWBKPT, along with a #define. Thus we cannot
define TRAP_HWBKPT to 4 beforehand, and so gdb_wait.h must be included
earlier; include it from linux-ptrace.h so it can never come afterwards.
gdb/ChangeLog:
* nat/linux-ptrace.c: Remove unnecessary reinclusion of
gdb_ptrace.h, and move including gdb_wait.h ...
* nat/linux-ptrace.h: ... to here.
